WINDOVJ-GONTROL MEANS.

Application filed February To all whom it may concern:

Be it known that I, WILLIAM C. GROB, a citizen of the United States, andaresident of Toledo, in the county of Lucas and State of Ohio, have made an Invention Appertaining to Window-Control Means; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use the same, reference. being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to control means for drop windows and particularly to means of this class adaptedto use in connection with the type of windows commonly used in closed automobiles and other vehicles, which windows have lowering movements when being opened.

The object of the invention is the provision of a control means of the character described which is simple, strong, and durable in its construction, capable of being easily and quickly applied and operable to eficiently look a glass in any position of adjustment.

The invention is fully. described in the following specification, and" while in its broader aspect it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the-accompanying drawings, in which,

I .Figure 1 is a fragmentary vertical section of an automobile door embodying the invention, with the window in lowered position. Fig. 2 is a reduced inner side View of the door with the window lowered and with the inner casing parts removed to expose the window and carrying means. Fig. 3 is an enlarged fragmentary view of a portion of the control means with the connected window partly shown and in section. Fig. 4 is a section on the line 14 in Fig. 3. Fig. 5 is an end view of the channel member of the control means. Fig. 6 is a perspective view of the fiber guide for the window carrying rod. Fig. 7 is an enlarged fragmentary View of a window carrying rod and attached lock bolt. Fig. 8 is a similar view thereof with the upper end of the rod in vertical section.

mentary plan view of one end portion of the window supporting channel. 7

Referring to the drawings, 1 designates a vehicle having a window opening 2 therein, and 3 a glass or window which is adapted to stand in position to closethe opening 2 or to be lowered into the lower portion of the door, which is made hollow for such purpose, as is customary in doors used in vehicles, such for instance, as automobiles.

The'window glass 3 is fitted at its lower edge into a channel bar 4:, preferably formed of sheet metal, such channel being substantially coextensive with the width of the glass and having its upper outer edge turned outwardly to form a stopflange 5. The inner side of the channel-bar has ears 6 struck outwardly from its ends in horizontal position with the ears extending attheir outer ends/beyond the ends of the bar and each being provided with a longitudinal slot or opening 7 toradjustably receiving the lower top of the window glass 3 through an openng in the adjacent end of the window sill 10 and is provided at its upper end with a block or head 11, which is mounted for re- 7 in a channeled guide bar '12. Qne ofthese guide-bars is mounted within the window casing at each side and at the inner side of the window glassS and is preferably formed from sheet metal, being channel form in cross-section with the outer or tree edges of its sides turned inward to form a retracted longitudinal opening 13 in the outer side of the bar throughout its.len'gth. Perforated ears 1% are struck from one side of the guide bar 1:2 and extend therefrom in'the plane of the channel base and are intended to receive screws15 for attaching the guide-bars to the respective sides of the window casing. The side of a guide-bar forming the bottom of the channel is provided with a series of longitudinally spaced openings 16 with which the inner end of a'lock-bolt 17 carposition of The lock-bolt 17 is mounted for longitudinal reciprocatory movements 1n the block 11 and has its inner end of stud form for projecting into a registering opening 16, and

its outer end projected through the guide bar from the window glass 3 to provide more room for gripping the bolt. The block 11 is slotted as shown at 18, above and below the opening therein through which the lockbolt projects, a pin 19 projecting with the upper slot from the bolt to prevent a turning of the bolt relative to the block and the lower slot containing a spring finger 20 mounted therein and in engagement with the bolt to normally retain the bolt in inwardly projected position. The inner end of the bolt is preferably tapered as shown to adapt it to be forced out of a guide bar opening 16 when an upward pressure is exerted on the bolt or window, but preventing any downward movement of the window carrying parts until'" the bolts have been manually withdrawn for such purpose.

In order to prevent rattling occasioned by a vibration of the rods 8, each rod projects through a fiber block 21 of felt or other "suitable material which is fitted at the lower end of the associated guide bar 12.

The lower edge of the glass 3, which seats in the channel bar 4 is bound with felt or other soft fibrous'material 22, as is custom ary in devices of this character, and the flange 5 of the channel bar is provided with a rubber bulfer 28, which, when the window is raised to its upward limit, strikes a sill flange 24L at the outer lower edge of the window opening 2. The bufier 23 comprises a bar-like strip of rubber which, is slotted to receive the flange 5, and is firmly secured to the flange by cementing the same thereto. This forms a very eflicient buffer and one 'which does not easily become separated from the carrying flange.

The weight of the window is at least partially counterbalanced by a lever arm 25, which is pivoted at one end within the in terior of the lower portion of the door at one side edge thereof and has its outer end provided with a roller on which the channel bar 4 rests. A coiled tension spring 26 connects the lever to the opposite side edge of the door frame and tendsto normally hold the free end of the lever arm in elevated position and to resist a lowering of the win- I wish it understood that my invention is not limited to any specific construction, ar-

rangement or form of the parts, as it is capable of embodiment in numerous forms,

reciprocatory movements in the casing, a

hollow guide bar secured to a side of the easing lengthwise thereof and having-a longitudinal opening in its outer side and a plurality of bolt receiving openings in its inner side spaced longitudinally of the bar, a

block mounted in the guide bar for reciprocatory movements longitudinally thereof,

a bolt carried by the block for reciprocatory movement-s transversely of the guide bar and adapted to have its inner end engage a registeringv opening in the inner side'of the guide bar, the outer end of the bolt extending through the outer opening of the guide 1 bar and forming a handle, a spring carried by th block and acting on the bolt to normally hold it in engagement with a registering opening, and a rod extending down fixedly attached to the lower edge of the window to causethe window and block to have movements in unison. I t v 2. In combination, means forming a win from the block through the guide bar and dow casing, a window mounted for vertical reciprocatory movements in the casing, a guid bar secured to a side of the window casing lengthwise thereof and formed of sheet metal bent to form a guide opening longitudinally therethrough which is rec tangular in cross-section and having a plu rality of longitudinally spaced catch openings in its inner side, a block rectangular in cross-section mounted in the guide bar for movements longitudinally thereof and having a slot therethrough, a catch bolt having a handle at itsouter end and a catch stud at its inner end projecting through the outer opening of the bar, the block slot and into a registering opening in the inner side of the bar, the bolt being reciprocally movable V in the block transversely thereof, a spring mounted in the block slot and engagingthe bolt to normally hold it in inwardly projected position, and a rod extending down through the guide bar and rigidly connecting the lower edge portion of the window and the block.

7 3. In combination, means forming a window casing, a window mounted for vertical reciprocatory movements in the casing, a channeled gulde bar secured to each inner side of the caslng lengthwlse thereof and having a longitudinal opening in its outer side and a plurality of vertically spaced lock-bolt receiving openings in its inner side, a block mounted in each guide-bar and guided for reciprocatory movements longitudinallythereof, a'bolt carried by the block for reciprocatory movements transversely thereof, and adapted to have its inner end engage a registering opening in the inner side of the guide bar, the outer end of the bolt extending out through the outer opening of the guide bar and forming a handle, a spring normally retaining the bolt in engagement with a registering opening, a rod extending down from each block through 10 the lower end of the guide bar and fixedly attached to the lower edge of the window at its adjacent side edge to cause the window and blocks to have movements in unison and a fiber block disposed within the lower end of each guide bar and having an opening through which the respective rod has close reciprocatory movements.

In testimony whereof, I have hereunto signed my name to this specification.
